"What are the uses of arithmetic?"

Teacher Mo was a little nervous in his first class, but fortunately, except for Li Gaoming, they were all acquaintances, which made Mo Dun relax a lot.

"For exams?" Cheng Chumo raised his hand high and said a wise saying.

"Uh-uh!" Merton was speechless.

"Settle accounts!" Zu Mingjun proposed a practical use.

"Doing the math is a great use of mathematics." Merton nodded.

However, the use of arithmetic is not limited to this, learning arithmetic, for the general can calculate the speed of the army, the time of the battlefield, the food and grass needed, and even the various conditions of the enemy army, how can such a general not win the battle.

Those who are in charge can calculate the country's taxes, spend taxes, and crack down on corrupt officials and corrupt officials through auditing, so as to govern the country reasonably. Ordinary people settle accounts and keep records of household expenses. Even street vendors have to learn arithmetic without a teacher. Arithmetic permeates everyone. ”

"We deal with arithmetic all the time, arithmetic is very important, and I love arithmetic more than any other subject! Today I want to tell you not only to learn arithmetic, but to learn the spirit.

In arithmetic, every number is a given, no change is allowed, one plus one is equal to two, will not be equal to three, will not be equal to any number, arithmetic is such a cold number, a board and a glance, to tell you the naked truth, you can not believe in anyone in the world or anything, but please believe in arithmetic, in this world, anyone can deceive you, but only arithmetic can't, you learn arithmetic, you control the right to see the truth. ”

Merton's words made everyone think, especially Li Gaoming, whose eyes flickered.

Even Qin Huaiyu and the three of them, who were originally going to make soy sauce, couldn't help but sit up straight and listened carefully.

"The arithmetic of the Mo family is different from the ten classics of arithmetic that you usually learn! The basis of everything is these ten numbers, zero, one, two, three, four, five, six, seven, eight, nine, these ten numbers. ”

Merton picked up a charcoal pen sharpened from charcoal and wrote down the ten numbers on a board.

Looking at the black ash in his hand, Morton secretly made up his mind to get the chalk out quickly, after all, the process is very simple.

"We've all learned this!" Yu Chi Baolin wondered.

"Really?" Merton smiled slightly, "What about these ten numbers?" ”

Merton wrote again under the blackboard, "0123456789." ”

"This is also a number? It can't be a ghost drawing! Everyone was confused by the crooked Arabic numerals.

"Merton, you're not going to learn witchcraft! It's a ghost drawing! Qin Huaiyu laughed.

"This is a number, but it's a Tianzhu number?" Li Gaoming said suddenly.

Merton glanced at Li Gaoming unexpectedly, but he didn't expect that he actually knew that these numbers were indeed Tianzhu numbers, but they were later spread around the world by Arab merchants and were honored as Arabic numerals.

"This is indeed the number of Tianzhu, Brother Gao Ming is so well-informed, this is the essence of arithmetic that the Mo family has learned from all the hard work of going to Tianzhu!" Mo Dun was not ashamed to put gold on the Mo family's face.

Merton casually wrote several sets of numbers on the blackboard with Chinese characters, and then used numbers to write the meaning of the representatives, and the five digits present all had a certain mathematical foundation and could easily understand.

It is better than not knowing, Arabic numerals have obvious advantages in large calculations, and they are easy to learn and clear at a glance.

"Is that too convenient?" Qin Huaiyu was very interested, if it was all about arithmetic, he would have learned it a long time ago.

"The ancestors of the Mo family are really admirable, I heard that a few years ago, a monk named Xuanzang made a grand wish to go to Tianzhu to seek the true scriptures, but I didn't expect that the ancestors of the Mo family had already sought the true scriptures of arithmetic from Tianzhu." Zu Mingjun said in surprise.

"Uh-uh!"

Mo Dun is a little blushing no matter how thick-skinned he is, and he acquiesced twice, and said sorry to Xuanzang in his heart, sharing the aura of your westward journey.

Merton simply taught five people addition and subtraction? made the five people exclaim constantly, compared to the calculations in the scriptures, it was simply too convenient.

Zu Mingjun was even more fascinated and obsessed with calculations.

"That's all for today's lesson." Merton breathed a long sigh of relief and interrupted the five of them reluctantly practicing, ending the day's schoolwork.

A few people reluctantly put down the quill pen in their hands, they found that the number of Tianzhu with the quill pen is much more concise and fast, how to write with the brush is not good, they have switched to the quill, it is also the first expansion of the quill pen!

"Brother Mo is broad-minded, and he is grateful to be able to teach the secrets of the Mo family's arithmetic." Li Gaoming sincerely admired.

Zu Mingjun also thanked him repeatedly, in contrast, the Mo family's arithmetic is already much more sophisticated than his ancestral family's ancestral arithmetic, just a Tianzhu number, it has already made Zu Mingjun unable to compare.

"Don't dare, don't dare!" Merton said modestly.

After all, the six were teenagers, and there were not so many rules, so they quickly got together and had a lot of fun.

Unconsciously it was time for dinner, and Morton said that he left his ancestor Mingjun and Li Gaoming to eat. As for Qin Huaiyu, the three of them are villains who can't be driven away.

"Then it's disrespectful! I have long heard that Brother Mo invented steamed buns to be extremely delicious, and the food of the Mo family must be unique. Li Gaoming said heartily.

"Then you will have a good mouth, today my Uncle Yu arrived, he is a must to make fish. It is said that when he was in the army, even His Majesty praised his cooking skills. Merton said.

"Oh! Then we're going to have a good taste," Li Gaoming said with a smile.

Since Li Gaoming had agreed to stay, Zu Mingjun was not modest and stayed.

"Here comes the fish!" The fish master brought the finished fish to the table, a sauerkraut fish, a braised fish, a steamed fish, plus a few side dishes, and a bowl of fragrant rice in front of each person, but three bowls of them were huge, obviously reserved for Qin Huaiyu and the three of them.

"A few young masters use it slowly!"

After Master Yu left, Morton pulled over a backrest chair specially made for him by Lao Zhangtou, and beckoned a few people to sit down, and the table was still a round table unique to Mojia Village, regardless of primary and secondary positions.

"This table and chair is also unique!" Li Gaoming looked at the round table, leaned back on the chair, and found that the chair was just able to support his waist, which was very comfortable.

"The Mo family has no rules, how can you be comfortable?" Mo Dun is very unaccustomed to the Tang Dynasty's habit of kneeling and eating, he has no way outside, and he has all changed to tables and chairs in Mo Mansion, anyway, he uses the Mo family as an excuse, and it doesn't seem weird.

As the owner, Merton was the first to move his chopsticks, picked up a piece of fish and started moving.
